Formalin 37 %, acid-free, stabilized

Formalin 37% acid-free and stabilized is a highly concentrated solution of formaldehyde used as a base for the preparation of histological fixation solutions. Formalin is an aqueous solution of formaldehyde, an aldehyde that cross-links proteins and nucleic acids to provide stable fixation of cell structures.
The 37% Formalin acid-free and stabilized form has two main advantages: First, it is free of acids that can damage tissue structures during fixation. Second, it is stabilized to prevent the formation of formaldehyde gases and polymers that could affect fixation properties.
To prepare a suitable fixation solution for histology, the 37% formalin is usually diluted with water and, if necessary, a buffer system. A common working concentration for tissue fixation is approximately 4-10% formalin. The 37% formalin solution is suitable for a wide range of applications in histology, cytology and pathology and is used to fix cell and tissue structures prior to staining and examination under the microscope.

Verwendung:

Bei der Fixierung werden alle in der Zelle ablaufenden Prozesse unterbrochen, unter möglichst optimaler Erhaltung des Zustandes und der Struktur des Gewebes. Biochemische Prozesse wie Autolyse, Verwesung und Fäulnis werden wirkungsvoll verhindert. Fixierlösung nach Stieve eignet sich zur Fixierung von Hodengewebe und Eierstockgewebe. Die Fixierlösung ist ausschließlich für die professionelle Anwendung als in-vitro Diagnostikum im histologischen Labor vorgesehen.
